A sex restraint is a restraint that is used during sexual activities. These types of restraints are most common in bondage play and BDSM scenes. They are designed to keep a submissive from escaping or moving. They are often used during acts such as erotic humiliation, cock-and-ball torture, and discipline. Being restrained helps increase a submissive's feelings of helplessness and humiliation; and makes it appear as though a dominant is in complete control.
There are a number of different types of sex restraints ranging from simple and inexpensive to intricate and costly. The most basic sex restraint is rope. Other sex restraints can include handcuffs, padded leather wrist cuffs, collars, body harnesses, full-body suits, bondage mitts, and under-the-bed restraint systems.
